MEANS FOR KNITTING NECKTIES.

Application filed September 2?, 1926.

The principal objects of the invention are, to produce in a tubularknitted tie a section with a smooth close knit stitch extending around aportion of the circumference of a tubular fabric, and to provide in atie formed with a fancy stitch a smooth inner side to the neck bandportion to enable it to be slipped freely around the neck.

A further object is to provide a simple form of mechanism which may bereadily attached to a standard knitting machine to accomplish thedesired result.

The principal feature of the invention consists in providing means formanipnlating the needles in such a manner as to knit a tuck stitch forhalf a. revolution of the member rotating about the needle cylinder anda plain stitch for the other half.

ln the accompanying drawings, Figure l is a plan view of a Brinton typeof knitting machine. I

Figure 2 is a side elevation of a portion of a machine looking in thedirection of arrow, Figure 1 and illustrating the arrangement of theattachments involved in the present invention.

Figure ving the special mechanism arranged each side of the needlecylinder for shifting the needles from a tuck stitch to a plain stitcheach half revolution.

la the Brinton type of knitting machine the stationary needle cylinder 1is sur-' rounded by a rotating carriage 2 which carries the patternwheels 3 and the tucking members 4!.- for manipulating the needles inthe cylinder to form tucked or plain stitches. This constructiml is awell known mecha nism and is illustrated in United States Patent 977,852of December 6, 1910 and United States Patent 953,122 of March 29, 1910.

Each tucking member 4- is formed with a triangular bevelled end 5 andsaid member tilts on a pivot in the bracket 6.

The tucking bar plunger 7 which is not a part .of this present inventionbut is part of the usual mechanism, is operated from the 5am drum 8 inthe ordinary manner to engage the bevelled end of the tucking barsastl'iey are carried past the plunger in the rotation of the carriage.

The present invention consists in applying to the standard knittingmachine as above 3 is a detail elevational view show- Serial No.138,085.

mentioned special devices for operating the tucking bars at certainperiods different from the ordinary mechanism and a plunger mechanism 9is arranged at one side of the rotatable carriage, substantially in aposition in right angular relation to the plunger 7 and diametricallyopposed to the plunger 9 is a rocker bar 10 pivotally mounted in abracket 11.

The plunger 9 here shown is operated by a platc12 which operates on apivot in the supporting bracket 13 and this plate is oscillated by a rod14L which is pivotally mounted in a bracket 15 secured to the frame ofthe machine and has an extension 16 extencing downwardly and restingupon the tam drum 17.

The drum 17 which operates intermittently is provided with a pluralityof cam projections i8 which as the drum rotates lift the extension end16 and operate the rod l-l to tilt the plunger plate on its pivot tooperate the plunger 9 to move it into or .out of the path of the tuckingbars d;

The operation of the tucker bar 4L causes a shift in the stitch producedand as the frame rotates about the needle cylinder a half circle iscompleted with a pattern or tuck stitch. The rocker bar 10 which ismounted diametrically opposite to the plunger 9 then operates to shiftthe position of the tucker 4E and change the stitch to a plain stitchfor the other half circle.

The rocker bar 10 is operated in a very simple manner by a rod 19 whichis pivotally mounted intermediate of its length on a bracket 20 and thedown-turned end 21 engages the surface of a cam 22 which is providedwith a semi-circular portion 23 of a larger diameter than the remainingportion.

The manipulation of the apparatus is very simple. The cam 22 and camdrum 17 operate with such relative movements as to ensure the operationof the plunger 9 and rocker member 10 in proper concert so that thetucking members l carried on the rotatable carriage will operate at suchperiods that they will manipulate the needles so as to knit a fancy ortuck stitch for half a revolution in each row and then knit a plain therelative portion of the circumference to be occupied either by the plainstitch or by the fancy stitch.

lVhen a tie is being knitted With the neck band portion formed with aplain back in the manner described, the ordinary tucker bar plunger 7 iscourse not operated but its place is taken by the plunger 9 and theroclier 10 which shift the stitch half way around independent the tuckerbar plunger 7. The result of this manipulation of the needles is thatthe machine produces a necktie knitted in tubular form With the insideof the ban d portion knitted in a short smooth stitch with the outsideportion knitted in a fancy stitch, While the body of the tie is knittedcompletely around with a fancy stitch by bringinginto action the tuckerbar plunger at the desired points in the length otthe tie as theknitting proceeds.

The attachment does not interfere in any manner with any 01 theoperating parts of the knitting niaehine and it is very simple to applyand costs very little to install.

What I claim as my invention is 1. In means tor lini ttinp; neckti s,the combination with a tubular knitting; machine luiving tucker barsarranged on the rotating *arriage and the usual means operativelyarranged at one side of the carriage for manipulating said tucker bars,of means operatiwly arran ed at one side of said carriage adapted tomanipulate the tucker bars at a predetermined point in advance oi: saidusual inanipulatiiugmeans, means operatively arranged. and adapted tomanipulate the tucker bars at a point substaz c ially equidistant beyondsaid usual manipulating means, and means for actuating the adan-ced anddelayed manipulating means when said usual manipulating; meins is atrest.

2. In a tubular knitting machine the combination with the rotatablecarriage having apair oi? diametrically opposed tucker bars arranged theeon and the usual tucker bar manipulating means, of separate mean rangedin diametriially opposite relation spaced equally either side of saidusual tucker bar manipulating means and adapted to operate said tuckerbars when the usual manipulating means is at rest in advance of andbeyond its point of operation to nevent the tuckin" of the stitches ineach course from a point in advance of the usual manipulating means to apoint therebeytmd.

3. In means for knitting neckties, the combination with a tubularknitting machine having tucker bars arranged on the rotating carriage,and the usual means operatively aranged. at one side of the carriage formanipulating said tucker bars of a tucker bar plunger arranged at oneside of the rotating head of the machine adapted to enu ap'e and tiltthe tucker bars in advance of usual manipulating means, mains forinter-mittently operating said plunger, means oi ieratively arranged atthe opposite side or" the head adapted to engage and reset the tuckerbar it a point beyond said usual manipulating means when the latter isat rest, and means for periodically operating said resetting member.

4. in a tubul: r knitting machine, the coml ination with the needlecylinder, having a rotatable 'arriage and. tucker bars radially mountedon said carriage co-operatingwith the needles of the cylinder, and theusual mea is operatively arranged at one side of the carriage adapted toengage and manipulate iaic tucker bars of a tumor bar plunger 'anged atone side of the head adapted to perate with said tucker bars in advancesaid mani 'iulaling; means, a rocker memiei ope 'atively engaging withsaid plunger, "1 :talilc *ain meinl er; ad: pted to operate sa l rocaermembers intermittently, and intelinittently operating means arranged atthe opposite side of the carriage from said tinker bar plunger adaptedto engage the tucker bars after said bars pass the usual niauipulatingmeans when the latter is at rest to ctiect t 10 changing of the stitchtherebeyond tor a. portion of the circumference of the cylinder.

in a tubular knitting machine, the coinbiuation with the needlecylinder, a rotatable Barriage, tucker liars radially mounted on saidcarriage co-ope 'ating with the needles of the cylinder, and the usualmeans operatively arranged at one side of said carriage adapted toengage and manipulate said tucker bars o t a tucker ba plunger arrangedat one side of said head, in 'ance oil said usual manipulating means,me: for intermittently operating said tucker b: r plunga pivotal rockermembe arranged at the )osite side of the l ead from said plunger lbeyond said usual manipulating means l adapted to engage the tucker.members, Wren tie usual mani ulating means is at rest, a pivotal rodconnected with said rocker member, and a cam adapted to op irate said lpi'mtal rod and said rocker member for a halt revolution ot thecylinder.
